In this paper, a methodology for fast re-design of antenna structures with respect to substrate parameters has been presented. The key component of our technique is an inverse surrogate model that is constructed using reference designs representing optimum antenna geometries for selected values of the substrate permittivity and thicknesses. The surrogate returns the values of antenna dimensions corresponding...
Fast scaling of geometry parameters that allows finding the structure dimensions for various operating frequencies is important to expedite the antenna design process. In this paper, we address the scaling problem for dual-band antennas so that optimum dimensions ensuring that the antenna operates at the two frequencies of choice can be obtained at minimum cost. Our approach exploits inverse surrogate...
In this paper, reduced-cost design optimization of dual-band antennas is investigated. The primary challenge here is the necessity of independent yet simultaneous handling of the antenna responses at two frequency bands. In order to alleviate this difficulty, a feature-based optimization approach is adopted where the design objectives are formulated in terms of the coordinates of suitably defined...
